SOFIA, March 27 (Xinhua) -- Bulgaria's triple jumper Gabriela Petrova tested positive for meldonium that has been headlined recently.

The 23-year-old European indoor triple jump silver medalist had taken the substance in 2015 while it was not yet listed as a banned substance by World Anti-Doping Agency (WADA), said her manager Venitsa Atanasova on Sunday.

The test was conducted in Bulgaria on February 6, she added.

Meldonium, added to the list of banned substances on January 1, 2016, became well known earlier this month after Russian tennis star Maria Sharapova announced she had tested positive for the drug at the Australian Open in January.

WADA said Thursday it had recorded 123 meldonium cases since the ban came into force.
